Tyre designations

E.g. 195/65 R 15 91 H
195 = Tyre width, mm
65 = Cross-section ratio (tyre
height to tyre width), %
R = Belt type: Radial
RF = Type: RunFlat
15 = Wheel diameter, inches
91 = Load index e.g. 91 is
equivalent to 615 kg
H = Speed code letter
Speed code letter:
Q = up to 100 mph
S = up to 112 mph
T = up to 118 mph
H = up to 130 mph
V = up to 150 mph
W = up to 168 mph

Tyre pressure

Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre deflation detection system.
Unscrew the valve cap.
Tyre pressure 3 217 and on the label
at the front passenger door.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to
tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre deflation detection
system
The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates yellow and a
warning message is displayed in the
Driver Information Centre with
Uplevel-Display. Stop immediately
and check tyre pressure.
Control indicator w 3 94.
